TROLLEYfWAGON.

SPECIFICATION forming part of Letters Patent No. 551,586, dated December17, 1895.

Application filed April 29, 1895- Serial No. 547,447- (No model.)

T at whom it may concern:

Be it known that I, GEORGE H. HULETT, a citizen of the United States,residing at Cleveland, in the county of Ouyahoga and State of Ohio, haveinvented certain new and useful Improvements in Trolley-Wagons, of whichthe following is a full, clear, and exact description.

My invention relates to that class of trolleywagons designed to run on abridge or trestle provided with a track, for the purpose of con veying abucket or other load from one end of said bridge or trestle to theother, in either direction; and it consists of the several partshereinafter fully set forth and claimed.

The object of my improvement is to provide a trolley-wagon of the classdesignated above, operated by drums driven by an ordinary hoisting orwinding engine, which is capable of being held at any desired point onits track, of automatically unlocking the load and lowering the same, ofagain elevating the load, relocking, and proceeding to another positionwhere these operations are again performed, and all without the use ofany stops fastened to the supporting bridge or trestle V as commonlyused with other wagons for this purpose.

'That my invention maybe seen and fully understood by those skilled inthe art, reference will be hadto the following specification and annexeddrawings forming a part thereof, in which Figure 1 is a vertical sectionof my trolleywagon, showing the hoisting-block in its normal or lockedposition; Fig. 2, a horizontal section on lines w at, Fig. 1, thehoisting-block removed; Fig. 3, a horizontal section on lines w 00, Fig.1, the upper guides removed, and

sheaves, ropes, &c necessary for operating.

the same.

Similar figures of reference designate like parts in the drawings andspecification.

The wagon proper or body consists of the side irons 1 1, joined by theend irons 2 2,

and said wagon is provided with the axles 3 3, and the wheels 4 whichsupport it on the rails 5 5. The four bearings 6 are bolted to the sideirons 1 1, two upon each iron, to receive and support the shafts '7 and8. The sheave 9 is fast on the center of the shaft 7 and the sheave 10is fast on the center of the shaft 8. Proj ecting from the end irons 2and 2 are the eyebolts 11 11. The end iron 2 extends downward betweenthe rails 5 at right angles to the side irons 1, and the iron 12,riveted at its upper terminus to saidside irons forward of the center,extends vertically downward between said rails, converging toward saidend iron 2,since said rails are inclined. The irons 2 and 12 form theends of a box-like frame, the sides of which consist of the plates 1313, riveted at their upper extremities to the side irons 1 and at theirvertical edges to said irons 2 and 12. The iron 12 is somewhat longerthan the iron 2, and from its base the lower edges of the plates 13incline upward at an angle of about thirty-five degrees and then extendhorizontally. From below a line connecting the intersection of theinclined and horizontal lower edges of each plate 13 with theintersection of said plate and the base of the iron 2, said plate isbent outward to form the wing 13, for the purpose hereinafter described.The guides 14 consist of angle-irons riveted to the inside of the plates13, the lower flanges 14 of said guides extending rearward from thebases of the irons 12 flush with the inclined edges of the plates 13nearly to the front corners of the wings 13', where they turn forward atan angle of about forty-five degrees to form the upper flanges 14 Theguides 15 consist of angle-irons riveted to the inside of the plates 13,the lower flanges 15" starting at the lower rear corners of the wings 13and extending upward at an angle of about forty-five degrees until wellon to the main portions of said plates, when they turn vertically upwardto form the flanges 15 Riveted to the inside of each plate 13, near andforward of the upper end of the guide 15, is the stop 16. The. stop 16has the horizontal flange 16 and the downwardly-extending flanges 16 16,and 16 The boxes 17 17 are riveted to the outside of the plates 13,opposite each other, and the latches 18 18 are pivoted on the inside ofsaid plates by the pins 19 19, which extend. through said plates andboxes, each latch 18 consisting of the nose 18, the lug 18 and the tail18. The latch-nose 18 11ermally rests against the base of thestop-fiange 1c. The slot 2 is cut in the top of the iron 12 to receivethe periphery of the sheave 9.

The hoisting-block is provided with the sheav 21, connected thereto bythe shaft 22, which projects each side of said block to engage thelatches 18, the guides 14 and 15, and the stop 10. A hole 23 extendsthrough the top of the bloek'20 and another through the base. The rope24 is secured at one end through the upper hole 23 of the block 20,passes up over the sheave 10, down around the sheave 21, up over thesheave 9, around the sheave 25 on the shaft 20, at the upper end of thetrestle 27, to the winding-drum 28. The drum 28 is supported on suitablebearings and controlled by the brake 2!).

The inclined trestle 27 is supported by the frame 30, and has at itslower end the bearing 31 for the shaft 32, on which is the sheave 83.The shaft 26 carries the sheave 34 in addition to the sheave 25. Theshafts 35 and 36 at the top of the frame 30 carry the sheaves 37 and 38,respectively, and the shaft 39 carries the drum 40, which is controlledby the brake 41. The rope 42 is fast at one end to the eyebolt 11 in theend iron 2 of the trolley-wagon, passes over the sheave 33, severaltimes around the drum 40, over the sheaves 3S and 37, and around thesheave 34 to be attached to the eyebolt 1.1, in the end iron 12 of saidwagon. The counterweight 43 is sus pended from the rope 42, between thesheaves 37 and 38 by means of the sheave 44, for the purpose of takingup the slack in said rope. The drum 28 is driven by an engine. (Notshown in the drawings.) The bucket 45 is suspended from thehoisting-block 20.

\Vith the wagon held at the lower end of the trestle 27 by the frictionproduced from the several turns of the rope 42 around the drum 40, whichis held by the brake 41, and the action of the counterweight 43, and thebucket 45 lowered, as shown in Fig. 6, the operation of my device is asfollows: Release the brake 29 from the drum 28, rotate said drum andwind up the rope 24 until the hoisting-block 20 with the attached bucket45 is elevated between the plates 13, the wings 13" serving to centersaid block in case of any lateral oscillation of the same, while theguideflanges 14 and the back edges of the latchtails 18 in front, andthe guide-flanges 15" in the rear, cause the shaft 22 to pass betweenthe guidehanges 15 and the stop-flanges 16 until the projecting ends ofsaid shaft are at the junctions of said flanges 10 and the stop flanges16, as indicated by the dotted lines 22 in Fig. 1. In their upwardpassage the projecting ends of the shaft 22 strike the under sides ofthe latch-lugs 18 and rock said latches until they stand, as shown bythe dotted lines 18 in Fig. 5, with the ends of said lugs against theintersections of the stopflanges 16 and 10 thereby causing said shaft topass upward to the point above indicated. As soon as the shaft 22 hascleared the lugs 18" the latches 1S swing back into their normalpositions with the noses 18 against the bases of the stop-flanges 16.The drum 40 is now released from the brake 41 and the drum 28 rotated inthe direction of the arrow, thereby drawing the wagon by the rope 24along the rails 5 on the wheels 4, and the shaft 22 settles down 011 thetops of the latch-lugs 18 ,as shown in Fig. 1. The turns of the rope 42around the drum 40 in conjunction with the counterweight 43 produce asufficient amount of friction to hold the wagon and load at any givenpoint, when the brake 41 is applied to said drum. As soon as the wagonarrives at the upper end of the trestle 27, or at any given placeintermediate of the ends, apply the brake 41 to the drum 40 and holdsaid wagon stationary. The continued rotation of the drum 28 winds upthe rope 24 and elevates the shaft 22 until its ends rest at thejunctions of the stop-flanges 16 and 16, as indicated by the dottedlines 22 in Fig. 1. A perpendicular line representing the center ofgravity of the hoisting'block 20 freely suspended from the sheaves 9 and10 passes through the point indicated by the dotted lines 22 Hence thetendency of said block forward when the shaft 22 is raised from thelatchlugs 18*, and in passing upward between the stop-flanges 16" and 16the ends of said shaft rock the latches 18 sufliciently to permit saidends to pass, as shown by the dotted lines 1S in Fig. 5. Since theheaviest parts of the latches 18 are below the pins 19 said latchesalways return to their normal position as soon as the shaft 22 clearsthem. N ow per- 1nit the rope 24 to unwind from the drum 28, said drumbeing governed by the brake 29, until the block 20 has passed below thewagon-frame and the bucket 45 is low enough to be relieved of itscontents. The shaft 22 is guided in its descent with the block 20, by

the stop-guides 10 and the upper front edges of the latches 18 untilbelow the pins ll), where the front edges of the latch-tails 18 areencountered and said latches rocked to permit said shaft to pass frombetween the plates 13, the guide-flanges 14 serving to facilitate thepassage in case of a forward oscillation of said block. tents, elevateit until the ends of the shaft 22 rest upon the latch-lugs 18", in themanner hereinbefore described, and controlling the drum 28 by the brake29, permit the wagon to descend by gravityto the'lower end of thetrestle 27, where it is again held and said bucket allowed to descendfor another load in. the same way as previously explained.

If the trestle is horizontal a rope attached at one end to the rear ofthe wagon, passed over a second sheave on the shaft 32 and having acounterweight on its opposite end, may be employed to draw said wagonback to the starting-point, or steam-power may be After freeingthebucket 45 of its con-v used as a propelling medium in bothdirections.

I do not wish to limit myself to the use of two sheaves on top of thewagon, since more or less than that number may be employed withoutdeparting from the nature of my invention. If one sheave only is used,the rope 24 will not, of course, pass around the block-sheave 21. Theobject of using two sheaves is to accelerate the movement of the blockand load.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination in atrolley Wagon, of a body, a frame provided Withthe outwardly extending wings 13: depending from said body, the angularflanged guides 14 and 15, and stops 16, fast on the inside of saidframe, and the rocking latches 18 pivoted Within said frame with theirnoses normally resting against the rear depending flanges of said stops,substantially as and for the purpose set forth.
